A 31-year-old pilot took off from Oakland, California, Thursday, flying a single-engine plane and hoping to make history. And her name just happens to be Amelia Earhart (no relation to her famous namesake).

The modern-day Earhart is planning to recreate the same journey; an around-the-world flight that's expected to take nearly three weeks.
